CARRIAGE-DOOR.

SPECIFICATION forming part of Letters Patent No. 729,409, dated May 26, 1903.

i Application filed December 20,1902. Serial No. 136,013. (No model.)

Myinvention relates to carriage-doors; and,

it consists of certain improvements in doors of that style of carriage familiarly known as a landaujthe object of my invention being to simplify the construction of the doorcasing and the sliding sash usually employed in carriage-doors of this character and the method of supporting said sliding sash.

My invention is fully illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the doorcasing, showing the sash extended and illustrating the improvements forming the subject of my invention. Fig. 2 is a vertical sectional view of the same on the line a a. Fig. 3 is a sectional view of a portion of the same, on an enlarged scale, illustrating a detail of myinvention; and Figs. 4 and 5are perspective views, also on an enlarged scale, illustrating further details of my invention.

In doors of this character as heretofore made the attaching of the necessary parts to support the sliding sash is attended with such cutting of the upper part of the door as to weaken the same, such cutting also pro viding numerous receptacles for the collection of water, resulting in the rapid rotting of the wood. In my structure, however, I avoid these objectionable features and provide supporting attachments for the sash that are simple in construction and attachment, making the sash very easy of manipulation.

In Fig. 1 of the drawings, 1 representsfthe door-casing proper,'and 2 the sliding sash, adapted to a recess 3 within the door 1. The sash is moved in and out of this recess by the usual straps (not shown) common to all forms of carriage-doors. To support the sash in the raised position, I provide the strip 5, bent as shown and secured, preferably, in a recess in the face of the lower part of the frame of the sash 2. The upper portion of the door-casing 1 is cut away at the front, as shown at 6, leaving a projecting rib 7, and the strip 5 extends over this projection 7 into the cut-away portion, as clearly shown in Fig. 3. In addition to this support the lower portion of the frame of the sash 2 is extended, as shown at 8, and to this extended portion the dowel-pins 9 are secured by any suitable means. Within the recess 3 of the door-casing 1 and secured to the outer wall of the same are the L-shaped plates 10, preferably set flush, as shown, and having apertures 11 in their lower part to receive the dowel-pins 9. It will be readily seen,therefore, that the engagement of the strip carried by the sash with the outer portion of the door and the engagement of the dowel-pins firmly holds the sash 2 in its raised position and prevents any rattling of the same and at the same time insures the holding of the sash against accidental removal or displacement.

To automatically assist the sash into the position shown in Figs. 2 and 3, I provide the spring 12, which is arranged within the recess 3, being carried by the inner portion of the door-casing and bearing against the lower extended portion of the sash.

The dowel-pins are preferably two in number, although more or less may be employed, as desired. These pins are carried by a plate set into the face of the door, as shown in Fig. 2, although they may be otherwise attached, audit will be noted that the dowels are set flush with the outer face of the sash, so that when the sash is supported in its raised position it will fit snugly within the recess against the outer wall of the same.

The strip 5 is preferably of the shape shown; but single projections arranged at intervals may be employed in place of the same Without departing from the invention. To prevent scratching or disfiguring of the strip 5, protecting tips or shoes 14 are employed, carried by the strip, as shown in Figs. 1 and 5. They may be made of any'suitable material.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. In a carriage-door, the combination of. the casing having a recessed portion, a sash movable therein, apertured plates arranged within the recessed portion of the door, dowelpins carried by the sash and adapted to engage said apertured plates, and a projecting member carried by the sash and engaging the upper portion of the recessed casing.

2. The combination in a door of the character described, of the casing having a recessed portion, a sash movable within said recessed portion, dowel-pins carried by said sash, apertured plates to receive the dowelpins carried within the recessed portion of the door, and springs carried by the door to engage the lower portion of the sash to press it into position when raised.

3. The combination in a door of the character described, of the casing having an internally-recessed portion 3 and an externallyrecessed portion 6, a sash movable Within the recessed portion 3, pins carried by said sash, apertnred plates to receive said pins carried within the recessed portion 3, springs carried by the door-casing to engage the lower portion of the sash and press it into position when raised, and a plate 5 carried by the sash and adapted to engage the upper recessed por- 20 JULIUS POLYA.
